Clayton Road is 2.35 miles long. Wood Pike Road is 1.7 miles long. Draw a quick picture to find the combined length of Clayton Road and Wood Pike Road

Answers

Answer:

4.05 miles.

Step-by-step explanation:

See the attached diagram. (not in scale)

Let AB is the Clayton Road and its length is 2.35 miles and BC is the Wood Pike Road and it is 1.7 miles long.

So, the combined length of Clayton Road and Wood Pike Road is AC (= AB + BC)

So, the length of AC will be (2.35 +1.7) miles = 4.05 miles. (Answer)

!!!HELP!!! PLEASE SHOW WORK SO I CAN UNDERSTAND!A ball shaped like a sphere has a radius of approximately 2 1/8 inches. Which of the following is the best estimate of the volume of the ball?
32 in³
11 in³
25 in³
17 in³

Answers


The only part of this problem that's the least bit tricky is knowing
the formula for the volume of a sphere.  Here is is:

          Volume of a sphere = (4/3) (pi) (radius of the sphere)³  .

Everything else is just arithmetic.

pi . . . use 3.14
Radius . . . 2-1/8 inches.  It'll be easier if we write that as  2.125 inches.

Now, just put the numbers into their places in the formula:

         Volume = (4/3) (pi) (radius of the sphere)³

                     = (4/3) (3.14) (2.125)³

and run that through your calculator.

When I run it through mine, I get  40.174 in³ .

None of the choices is anywhere near that number.
I'm worried, and I don't understand that.

Maybe we should look back at the question, and notice that
it says "estimate" ... something you do quickly in your head.

OK.  We know the real formula ...   Volume = (4/3) (pi) (radius)³ .
How could we estimate this quickly in our head?

pi . . . instead of 3.14, just use 3

radius . . . instead of 2-1/8, just use 2 .  Then (radius)³ = 2 x 2 x 2 = 8

Then  (4/3) (pi) (radius)³ = (4/3) (3) (8) = (4/3) of 24  =  32 .

Well now, will you look at that !  I guess that's where the 32 came from
on the list of choices.
